I have a bit of a cardigan addiction. I wear them constantly, both in the summer (chilly office A.C.) and colder months (instant winterizer for sleeveless dresses!), and I pretty much always have one slung over my desk chair or stuffed in my bag. Black cardigans are a particular weakness--they go with everything, and as a result, I buy them over and over again. So, my cardigan obsession was just one of the reasons I gravitated towards this dress. Not only does the black and white color scheme make the perfect palette for showing off a favorite neon bag or pair of glitter heels, but get this: The black "cardigan" part isn't a cardigan at all. It's part of the dress. How cool is that? A dress that comes with its own built-in cardigan? Talk about love at first sight.
